Status Report

• Feixiong got 56 nodes working for an experiment.
  • 40 nodes were able to run the GNRS server

Discussion

• Generating topologies
• What to evaluate
  • Latency per request (at client)
    • With and without cache
  • Throughput vs number of requests
  • Staleness (update latency)
  • Consistency
  • Failure
    • Definition of failure
    • Rate of failure
  • How to handle offline nodes (TTL)
• K-replica policies
  • Lowest-latency replica only
  • Two random, use the first response
• Cache replacement policies need to be revisited
  • Simple LRU for now
• Time to live
  • TTL and expire time for each binding

New Tasks

• Get "latency" values for 50 nodes on the grid
  • Fully-connected, random-delay topology (5 nodes, 10 nodes, 20 nodes, 50 nodes)
  • need to create an gnrs image that can work for different types of i7 node
